A sewing installation for the production of a lined pocket opening on a workpiece comprises a stand on which a working plate is supported. A cutting device for the production of corner cuts in the workpiece is disposed underneath the working plate. This cutting device is held on a support which lodges in the stand pivotally about an axis so that the cutting device can be moved into a position in which it is free from the working plate.

Sewing installation for the production of a piped pocket opening

A sewing installation for the production of a piped pocket opening in a cloth workpiece comprises two cutting units each with a corner cutting knife, which have two knives each. For the production of straight or diagonal corner cuts, one knife of a corner cutting knife is displaceable and adjustable in the direction of the incision which substantially constitutes the pocket opening.

A sewing machine having a machine arm, a rest for the material being sewn and a device for producing buttonholes, which comprises a cutting knife and a plurality of cutting blocks of respectively different lengths which are arranged on a common carrier. The buttonhole device is acted upon by an actuating device that can be moved from an upper position into a lower position, the cutting knife is arranged in a stationary manner underneath the sewing material, and the cutting block is lowered by the actuating device onto the cutting knife.

Buttonhole sewing machine having a plurality of cutting blocks

An automatic sewing apparatus comprises a workpiece holder which is designed for manipulation of a pocket flap. It comprises a flap clamp and a transfer clamp and a clamp. During the sewing of a first flap seam, the flap is held by the flap clamp and the clamp. In this case, the transfer clamp is positioned under the flap. Then the flap clamp is released and the clamp is disengaged and simultaneously the transfer clamp is displaced such that on the one hand the flap is folded down over the first flap seam and is simultaneously held in vicinity to the second flap seam to be produced.
